Most people here seem to think that the interests and concerns of studios, producers, and theaters are essentially the same, and that if something (like intermissions) would benefit theaters, the studios would do it. This hasn’t been the case since the 1948 SCOTUS anti-trust ruling, aka the Paramount Decree, that prohibited studios from owning theaters.
The interests of producers and exhibitors (i.e., theaters) have been diverging steadily since then, and the gulf between them has never been wider. With the advent of television, VCRs, DVDs, giant flat-screen TVs, and streaming, the declining financial importance to the studios of (shrinking) theatrical release windows means that producers no longer give a fig for what theater operators need or want. It’s only more than a century of tradition, the preference of a few powerful auteurs, and the power of the Oscars, which still require a minimum theatrical release, that keeps most films opening somewhat exclusively in theaters, and not going straight to streaming.
So the reason that so few films now have intermissions has nothing to do with what the exhibitors want. They are the low men on the totem pole. (Is that still an acceptable expression?) There were no projection-related technical reasons for intermissions by the 1970s, and any conceivable such issues were completely eliminated by the advent of digital projection in 2005.
So the only reason for intermissions today is that a director who is powerful enough (think Spielberg, Scorsese, Cameron, Tarantino, Nolan) wants them. In the case of several recent long films, like Scorsese’s Killers of the Flower Moon (3:26), theaters that added intermissions at the request of customers were threatened with legal action by the studios for violating the terms of their contract.
However, according to this 2023 Variety article, movie run times have been increasing, and exhibitors are trying to persuade the studios to permit intermissions. Whether producers will go along is yet to be seen.
When I was in my 20s and 30s and went to movies with my dad, I snickered behind his back because he had to use the rest room before and after the movie! I’m 69 now, and laughing out of the other side of my mouth. I’m lucky if I can make it through a two-hour movie without a break.
Back when? Movie theaters in the US allowed smoking until the 1970s or '80s. Here’s a NYT item in 1976 that General Cinema Corp. was going to ban smoking in its 650 theaters (but still allow it in the lobbies and lounges).
